  • Experience with Azure DevOps, CI/CD, and production delivery practices.
  • Experience in payments, financial services, regulated systems, or other security-sensitive environments.
  • Experience with compliance automation, web-scraping systems, or high-risk transaction processing.
  • Experience with observability, secure software design, and production incident ownership.
  • Experience mentoring engineers or helping define team practices, if leadership responsibilities are confirmed.
  • Growth without limits: build your skills through mentorship, internal TechTalks, challenging projects, and a dedicated annual learning budget
  • Competitive compensation: get recognition that reflects your skills and impact, with regular performance and compensation reviews
